'Twilight: Eclipse' rounds out casting with Leah, Seth

Despite the "Bandslam" star's interest in the role of Leah Clearwater in the "Twilight" movies, "Eclipse" began shooting with Julia Jones in the role of the teen wolf. In addition, 15-year-old stuntman BooBoo Stewart nabbed the role of Leah's brother Seth.

Leah and Seth become full-on werewolves during the events of Stephenie Meyer's novel "New Moon," though they're not truly given character until "Eclipse." At that point, Leah -- the pack's only female werewolf -- and Seth team up with Jacob Black to protect vampire Edward and human Bella from an army of new bloodsuckers.
